'6 Claims. (Cl. 229-19) This invention relates to a shipping container for one "or more elongated articles, 'WhlCh is well suited for re- -ceivingVenetian blinds andheadbars and bottom bars therefor.

The container of the-present invention is formed of .tWo, -open-ended, boxlike-cntainergparts, one of which istelescoped over theop'en end of the other. The container is particularly well-suitedfor Venetian blinds of varying-widths and for bundles of varying lengths of -V'enetian blind head bars and bottom bars, the same size rcontainerserving overa substantial range of sizes by va rying the. amount by which the outer containerpart is telescoped over the open end of the inner container part.

"in-the. form shownof thepresent invention, the inner container part may be folded into boxlike form'about'the article or articles to be received, the container part being foldedfrom a single sheet of paperboard which. haspreviously been cut and scoredto facilitate folding. It is unnecessary. to glue, staple,v or. otherwise secure the inner container part, the outer container part serving to hold it in folded, boxlike form.

The outer container part, 7 whichv :is folded generally similarlyto'the. inner container-part, requires only a minimunramount of tape which serves to holdit against 1 unfolding and: also to-secure it. intelescoped relation to .the innen container partsotas to seal the.container for shipping.

w-Among the objects of the present invention areto pro- -vide-a strongand rigid paperboard: container ofvariable length for reception of one .or more elongated articles of varying length; to provide such a/container-that is easily folded, packed, and sealed; -to, .provide*such -a container that is easilypnsealedg. to provide :such a. container that is economical and easytto manufacture;.- andto generally improve containers of the type: described.

The inner container-part-l2zis preferably folded about the articleor articles to be packed as-indicatedinl-Tigfl This is accomplished by' laying-thezarticleor articles on athe side 17 of the container part with one end- 'oft-he articleadjacent the scorei line separating this side-ofthe container fromthe. end '19.

Then,=thei'side .16' may be folded over through theposition shown 'in inner container part.12- and-is foldedinto open," boxlike form in a generally similar manner. -Referring to Fig. 2,

the blank for the outer container partcomprises two side portions 24 and25.connected by antend portion "26,-the side; portions-being separated from 'the-endportionby Patented ;Nov. 1, 1.955 I score lines, indicated by broken lines, to facilitate folding. The length of the side portions 24 and 25 may be about the same as the length of the side portions 16 and 17 but the width of these portions and of the end portion 26 is slightly greater in order to permit the folded outer container part to be telescoped over the inner container part.

Side flaps 27, 27 and 29, 29 project laterally from side portions 24 and 25, respectively, these side flaps being separated from the portions 24 and 25 by score lines as indicated and the side flaps preferably likewise being slightly larger in order to facilitate telescoping of the outer container part over the inner container part. End flaps 30, 30 project from the ends of the side flaps 27, 27 adjacent the end portion 26, these end flaps corresponding generally to the end flaps 22, 22 of the container part 12.

A marginal flap 31 extends from the side of each side flap 27 opposite to the end flap 30, these flaps being separated from the side flaps 27, 27 by a double score to facilitate bending these flaps back about the adjacent edge of the side flaps 29. Initially, the ends of the marginal flaps 31, 31 may lie generally along the line of the end of the side portion 24; but, after folding the container into boxlike form as indicated in Fig. 4, both side portions 24 and 25 will extend beyond the side flaps to facilitate sealing the carton, as will be explained. Four locking flaps 32 are formed from the outer corners of the side portions 24 and 25 as indicated in Fig. 2.

The outer container part 14 is first folded into boxlike form in generally the same manner as the inner container part 12. The side flaps 27, 27 are folded up from the plane of the side portion 24 and the end flaps 30, 30 folded inwardly to a position lying along the score line separating the side portion 24 and end portion 26. Then the side flaps 29, 29 are folded up from the plane of the side portion 25 and the side portion 25 folded up into parallel relation with the side portion 24, the side flaps 29, 29 being entered inside of the flaps 27, 27. Then, the marginal flaps 31, 31 are folded inward about the adjacent edge of the side flaps 29, 29. These flaps are held in folded position by folding the locking flaps 32 inwardly against the inner surface of the side portions 24 and 25 so as to overlie the ends of the marginal flaps 31, 31 (see Fig. 4).

The outer container part 14 may then be telescoped over the article or articles to be packed and the open end of the inner container part 11, the outer container part being telescoped until the end of the container formed by the end flaps 30, 30 and the end portion 26 rests against the end of the contained article.

As above described, the side portions 24 and 25 of the outer container part 14 project beyond the other two sides of the container part formed by the flaps 27, 27 and 29, 29. In sealing the container, industrial sealing tape 15, such as gummed paper or fiberglass-reinforced cellophane tape, may be placed about the four corners of the container, portions of the entire width of the tape lying on the outer surface of the side flaps 20, 20 of the inner container part 12 and other portions of the entire width of the tape lying on the outside surface of the ends of side portions 24 and 25. The tape may be a single length of tape extending about the circumference of the container or may be a separate piece at each corner, as indicated in Fig. 6. The tape 15 not only serves to hold the inner and outer container parts 12 and 14 in telescoped relation, but additionally serves to hold the side portions 24 and 25 of the outer container part from separating.

Since the outer container part 14 is a snug fit over the inner container part 12, the inner container part holds the locking flaps 32 and the marginal flaps 31, 31 against unfolding. The marginal flaps 31, 31 and locking flaps 32 serve as a slightly resilient cushion between the inner and outer container parts 12 and 14 and assure a tight fit between these parts.

Substantially all portions of the sealing tape 15 are in contact with either the inner or outer conta e p rts,

there being very little bridging of the tape between the inner and outer container parts. In this connection, the reduced width of the extremities of the side portions 24 and 25 of the outer container part 14, caused by folding inwardly the locking flaps 32, substantially reduces the bridging of the sealing tape 15 and contributes to a much stronger and superior sealing of the container.
